[Editor Note: Last September, SeniorsSkiing.com published an article about layering prompted by an unfortunate experience in extremely cold weather when we over-layered and paid the price for it. This year, here’s a list of tips from Val E., our new correspondent who has deep background in the ski industry. He’s bringing us up to date on the new technology view of layering. Here’s his advice.]

Thoughts On Hats, Gloves, Socks:

  • A thin skull cap (1/32 inch thick) doesn’t add much warmth to a helmet (which has about an inch of foam). However, a balaclava protects your face, neck areas exposed to cold air.
  • Let’s be real, glove liners (very thin gloves made out of silk, wool or synthetic fabric) add very little warmth to a decent pair of gloves. They also separate your fingers if you’re wearing outer mittens. But liners do keep your hands drier by taking moisture off your skin, and, most importantly, they protect your skin from exposure when you take your outer gloves off.
  • Socks must be skiing-specific,(i.e., not hunting socks, etc.) made of a synthetic or wool/synthetic combination. And, a ski sock must be knee high, no exceptions. All real ski socks are, anyway. Thicker is not always better, because comfort, staying dry and avoiding blisters are critical. Avoid old school equally thick tube shape socks. And, only one sock per boot! Never use sock liner, no matter what the propaganda says. Feel cold? Get the boot fitting right, install heaters, take a break inside.

 Base Layer Thoughts:

  • Lightweight (thick as a nylon sock) –For warm weather or people who “run hot”
  • Midweight (thick as a cotton t-shirt) –For most conditions or most people
  • Heavyweight (thick as a warm flannel) –For cold conditions or people who “run cold”
  • Three-quarter base layer pants are relatively new and very practical, because a skier doesn’t need to have pants extend into the boots which can get bunched up and cause comfort and  circulation problems.
  •  Compression base layers (shirts, pants, socks) are becoming more popular. Manufacturers claim they support muscles, improve recovery time, and more. There are skiers who love them and skiers who don’t. Try a pair of compression socks to see what you think. [Editor Note: See our article on Injinji compression toe socks here.]
  • These days, some base and mid layers have extended sleeves with so called thumb loops to keep the sleeves in place. Majority of outer jackets on the market have sleeves cut longer than we are accustomed to. You can adjust them with Velcro closures. The idea is to keep the wrist area well covered for people of different height.

Outer Layer Thoughts:

If you ski most of the time in:

  • Wet conditions (high humidity, wet snow, rain, wind), then stick to pants and jackets made of the best waterproof/breathable fabric (Gore-tex, Dermizax).
  • Dry climate and not very cold conditions with moderate snowfall, you can select clothing made of any breathable membrane fabric.
  • Warm conditions with no or limited precipitation,  then try a soft shell jacket. These are highly breathable, windproof and water resistant (but not waterproof!).
  • Many companies use the idea of mapping insulation or “body-mapped clothing” in mid and outer layers, putting more insulation in the zones, where the skiers need them most. Mapping for women and men is different.

And here’s a short video produced by Berghaus on its experiments with body mapped outer layers in Greenland. Worth a look.

Product Review: NuDown Parkas and Vests Use Pumped Air to Stay Warm

Reduces Layering. Improves On-Hill Comfort.

For the past several weeks, I’ve been skiing in a NuDown parka designed to keep you comfortable regardless of outside temperature and without dressing in multiple layers. It utilizes a hand-operated air pump system to create an adjustable layer of air, which, warmed by the body, serves as an effective insulator against the elements.

It works. My problem is that, given the relatively warm temperatures since using the parka, I’ve been unable to test it in extreme cold conditions.

Between the outer and inner shells is a bladder with a zigzag pattern of air chambers. A small and easy to use hand pump in the left pocket inflates the chambers. On brisk mornings, I’ve found that 15 pumps is sufficient to be comfortable. Later, when it warms, I press the release valve, which deflates the parka.

Typically, the more cold I expect, the more layers I wear, a technique that can get a bit bulky and result in in overheating as the day warms.

This parka, new to the market, and going by the name NuDown, eliminates the layering hassle. Having used it in not overly cold conditions, my positive experience and common sense tells me that it should perform effectively when it gets truly frigid.

The NuDown parka also is good-looking, even when fully inflated. And it sports a neat little zipper pocket near the left wrist for an RFID lift pass—the increasingly popular lift-pass technology used to open gate to the lift. Simply wave your arm to enter and save the chest pocket for your cell phone. A very nice detail.

The zip-off hood is sized to cover a helmet.

There’s been a lot written about improvements in down and being sensitive to the animal rights issues associated with down production. Some downs are processed not to clump when wet. Some are advertised as being humane. NuDown substitutes air for feathers. It lets you leave the layers at home, and it lets you adjust the air insulation so you can be comfortable in a variety of conditions. In the lodge, it’s a conversation starter when people ask about the zigzag air chambers, especially when inflated.

It’s not as light as down, but, in my experience, that’s not an issue.

NuDown technology currently is available in men’s and women’s parkas and vests. It will be available at retail in the fall and, like most everything else in the world, is available on line. Currently the NuDown site is offering a 30 percent discount.
